I have a bit issue after set up sample rate on site as below,
ga('create', 'UA-XXXXXXX-X', 'auto', {'sampleRate': 6});
we don't see the message at the top of the report that says "This report is based on N% of sessions" at all. Could you advise? or there's any another way to check in GA Dashboard?
You have set the sample rate at 6%. Hence sending traffic activity of only six percent of your site users(not sessions) to Google Analytics.
A similar question posted in the past:

Are you seeing any drop in traffic since switching the sample rate to 6%?
